ID #1165 Undefined switching of a floating channel with binary input BE/S x.20.2.1 Carolina Bachenheimer-Schaefer 05.10.2016 12:10 0 Comments If potential-free scanning is used, the signal cables should not be routed together with live cables. This can result in capacitive voltage coupling, which can be detected as a switching command. Tags: Gateway, KNX, TP
